Crystallization Properties of Ge-Se-Bi Thermoelectric Glasses

Abstract:

In the present work, a series of glass samples in Ge-Se-Bi system are prepared. XRD analysis is made on samples for identifying the type of precipitated crystals from glass matrices. Effects of glass matrix composition on crystallization behaviors are discussed. Results show that Ge and Bi content of glasses in the Ge-Se-Bi system are closely related to the precipitation of pure Bi2Se3 thermoelectric crystal phase. The optimal glass-ceramic composition is presented.
